Changes in classification introduced in the 1993 study are indicated in italic and account for a portion of the changes suggested in the original classifications.
Dry land forests: Include evergreen, coniferous, deciduous. mixed and secondary forests.
Evergreen forest: Multi-storey forest consisting of more than 80% of evergreen species The main characteristic species are Dipterocarpus dyeri. D. corbatus. D. Alatus. Anisoptera cochinchinensis, Hopea adorata, H. pierrei, Roherea vulgaris, Syzygium spp.
Coniferous forest: Refers to Pines forest (mainly in Kirirom area).
Deciduous forest: Dry deciduous Dipterocarp forest. Most characteristic species are forest resistant and have thick bark. such as Dipterocarpus intricatus, D. optusifolius, Shorea obtusa, Terminalia tomentosa, etc.
Mixed forest: Forests of deciduous and evergreen species, where deciduous species represent more than 50 percent of the stand.
Secondary forest: Refers to open forest with growth mostly after shifting cultivation.
Edaphic Forests: Include flooded, flooded secondary and mangrove forests.
Flooded forest: Refers to flooded forest around the Tonle Sap Lake.
Flooded secondary forest: Refers to flooded secondary forest with open canopy and regrowth after cultivation or cutting.
Mangrove forest: Refers to mangrove forest (on tidal saline water) and rear mangrove forest.
